lMPROVEMENT' m ENVELO'PES.

Specification forming part of Letters Patent No. 140,204, dated J une 24,1873; application'filed April 26, 1873.

To all whom it may concern:

Be it known that I, SOL.-KUH, of J efierson, in the county of Greene, and in the State of Iowa, have invented certain new and useful Improvements in Envelopes; and do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings and to the let-' ters of reference marked thereon m'akingapart of this specification. V The nature of my invention consists inan envelope provided with a sanded or emeryized back, and also inmaking an envelope wider at one end than at the other, and with incisions a short distance from and parallelwith the wider end, all of whioh'will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains' to make and use the same I will now proceed to describe its construction and operation, referring to the annexed drawing, inwhich- I Figure 1 shows the back of my envelope section of the same.

A represents the front and B the back of my envelope. The envelope may be made of any kind of paper, but the back B is made stifl' by means of sanded or emeryized paper, pasted or otherwise permanently attached to the same; or the back may be made of such before use; and Fig. 2, after use. Fig. 3 is a stifl'er material while the front only is made of the usual paper. a

Letters are frequently miscarried or misdelivered by sticking together caused by the post-masters stamp, and also because in the handling and tying up of the mail matter the corners or edges of larger letters are apt to fold themselves over the adjoining ones, and

thereby hold them firmly as if they were only one. These difficulties are entirely obviated by the use of the stiff-back envelope, as the post-masters stamp on the front ofour envelope will not adhere to the back'of the one on top .of it, and the corners can not-bend down so easily.

The envelope is made wider at one end than .at the other, and across the wider end are a number of incisions, a a, in the back B, forming a line parallel with the end of the envelope. This facilitates the tearing 01f of the envelope without injury to the contents, and the piece so torn ofl' may be used as a cover for the end of the envelope, as shown-in Fig. 2, so that the used envelopes may afterward be employed as receptacles for various articles about the house.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, isy 1. An envelope constructed wider atone end than at the other, and the wide end provided with a series of slits or perforations, a, constituting a defined severing-line, to pro-, vide a cover, as and for the purposes set forth.

2. An envelope whose back is provided with, a sanded or other gritty coating, as and for the purposes set forth.

In testimony that I claim the foregoing l have hereunto set my hand this 10th day of I April, 1873.
